AC/DC, one of the last big holdouts to make their music available on iTunes, have finally relented. Starting today, the Australian hard-rock band's entire catalog is now available digitally — all on iTunes.

Eternal schoolboy Angus Young is still at the head of the class. Readers of Australian Guitar Magazine recently named the AC/DC axeman the best Australian guitarist of all time.

He wrenches solos from the neck of a battered Gibson SG with all the grace of a drunken dentist; his fingers practically trip over the frets. Hands like his are most often found on pork butchers, pinball players and wrist wrestlers. Yet Angus Young's hands have fashioned some of the most memorable guitar riffs in rock history, driving such classic scorchers as "Whole Lotta Rosie," "Highway To Hell" and "You Shook Me All Night Long."
